Definitions
- the invention relates to the field of power electronics. It is based on a converter system and method for operating such a converter system according to the preamble of the independent claims.
- an inverter system comprises a converter unit, to whose DC voltage side a DC voltage circuit is connected.
- On the AC side of the inverter usually an electrical AC voltage network and / or an electrical load, such as a rotating electrical machine or a transformer is connected, wherein any electrical load is conceivable.
- a Kurzschliesserscchez is usually connected to the AC side depending on the application.
- An inverter system of the type described above with a short-circuiting circuit is shown, for example, in US 2005/0281065 A1 and in US 2007/0291426 A1. In case of exceeding the current carrying capacity of the inverter unit, the switches of the short-circuiting circuit are turned on and the AC voltage side the converter unit short-circuited via a Kurzschliesserwiderstand the Kurzschliesserscnies.
- thyristors Due to the high demands on current carrying capacity coupled with low component costs, it makes sense to use thyristors as switches of the short-circuiting circuit, as disclosed by way of example in US 2007/0291426 A1. However, thyristors can not be actively switched off or extinguished. The switching off of a thyristor is possible only in the zero crossing of the current to be carried, thereby consuming additional "erase circuits" are necessary.
- Double-fed asynchronous machines as electrical load in addition to their use in classical rotating frequency converters, are increasingly being used in variable-speed pumped storage power plants.
- the "unbundling" of power generation and transmission often introduces a Grid Code, which defines the respective connection conditions to the electrical supply network.
- the connected power plants and frequency converter systems should remain connected to the electrical supply network during temporary voltage dips and should partially actively contribute to voltage sup- port by means of a regulated feed-in of reactive current as specified in the respective Grid Code
- a regulated feed-in of reactive current as specified in the respective Grid Code
- the rotor winding of double-fed asynchronous machines with alternating current in the case of voltage dips, sees a higher current in the short term than during normal operation
- the rotor clamping In order to limit the permissible level for the rotor of the machine, the abovementioned short-circuiting circuits with a multiplicity of thyristors are used.
- Kurschliesserscen protect converter unit and machine reliably by short circuit the rotor winding in case of failure.
- the object of the invention is therefore to provide an improved with respect to the prior art inverter system with a thyristors having Kurzschliesserscnies, in which the thyristors of the Kurzschliesserscnies can be easily turned off and which is particularly simple. Furthermore, it is an object of the invention to provide a method by means of which the converter system can be operated in a particularly simple manner and the thyristors of the Kurzschliesserscnies can be switched off easily, quickly and safely.

- the current through the converter unit is monitored for a threshold value and when the threshold value is exceeded, the thyristors are switched on by applying a switch-on signal, so that the AC side of the converter unit is connected to the at least two short-circuit resistors.
- a voltage limiting unit for limiting an overvoltage of the DC voltage circuit is connected to the DC voltage circuit, wherein the voltage limiting unit is connected to the at least two short-circuit resistors. After falling below the threshold value, the converter unit switches the AC side of the inverter unit to the voltage zero point of the DC voltage circuit and the switch-on signal is no longer applied.
- the voltage limiting unit connects the at least two Kurzschliesserwiderstande for an adjustable period of time with the DC voltage circuit, after which the inverter unit separates the AC side of the inverter unit again from the voltage zero point of the DC circuit.
- the inverter system also includes a converter unit to whose DC side a DC circuit is connected and to whose AC side a short-circuit is connected, the short-circuit having a plurality of thyristors and a Kurzschliesserwiderstand.
- the current through the converter unit is monitored for a threshold value and, if exceeded, th the threshold value, the thyristors are turned on by applying a turn-on, so that the AC side of the inverter unit is connected to the Kurzschliesserwiderstand.

- the voltage limiting unit connects the Kurzschliesserwiderstand for an adjustable period of time with the DC circuit, after which the inverter unit separates the AC side of the inverter again from the negative or positive voltage point of the DC circuit.
- the converter system for switching at least three voltage levels or for switching two voltage levels is thus very simple and accordingly robust. If the thyristors of the short-circuiting circuit switched on, for example, due to an overcurrent, it is advantageously possible by means of the voltage limiting unit to turn off the thyristors again easily, quickly and safely.

- the DC voltage side is connected to the DC side and the short-circuiting circuit is connected to the AC side, the short-circuiting circuit having a plurality of thyristors and a short-circuiting resistor.
- the current through the converter unit is now also monitored for a threshold value and when the threshold value is exceeded, the thyristors are switched on by applying a switch-on signal, so that the AC side of the converter unit is connected to the short-circuit resistor.
- the Kurzschliesserwiderstand takes over the overcurrent until the threshold is fallen below again.
